Title: Constant voltage power supply circuit
Inventor: YOSHIZAWA MASAYUKI
IPC: G05F3/24
Filed: 1982-02-19
Abstract: PURPOSE:To eliminate the effect from ambient temperature change, by using a depletion type transistor (TR) for the current source of an operational amplifier and converting the gate voltage to the same potential as the source voltage. CONSTITUTION:An offset voltage is formed by changing the surface density under gates of TRs n3, n4 and the voltage is outputted at a node 1. The offset voltage includes the difference of the threshold voltages of the TRsp1, p2 and also the difference between betan of the TRsn3, n4 effected with the temperature characteristics, i.e., the difference between betap of the TRsP1, P2. The difference between the betan and betap is taken betan and betap, the threshold voltage of a TRn5 is  taken as Vthn and the gate voltage of the TRn5 is taken as VG, then an offset  voltage VOFF is expressed by Equation I. Since the voltage VG is changed according to the temperature change, a depletion type TRn5 is used. Further, the  gate voltage and the source potential are taken the same. Thus, the constant  current source circuit against the temperature change is obtained.

Abstract: PURPOSE:To prevent an electrical breakdown between an MR element and an electrode, and the discharge breakdown of a thin film head by connecting the electrode exposed on a head face among the electrodes conducted from both the edges of the MR element with a ground potential. CONSTITUTION:An MR element 1 is arranged vertically to a head face (a), one electrode 2a of two electrodes 2a and 2b conducted from both the edges of the MR element 1 is exposed on the head face (a), and the other electrode 2b is not exposed on the head face (a).

Abstract: PURPOSE:To obtain a semiconductor storage device having the high integration density by using a gate electrode layer for isolating elements as one power- supply interconnection layer, and forming a conducting layer for a bit line at the wiring level higher than the interconnection layer. CONSTITUTION:A grounding potential is imparted to isolating gate electrode layers GT0-GT2, and the gate electrode layers are used as grounding-side power- supply interconnection layers.

In this element isolating structure, the gate interval can be reduced to the machining limit of each of gate electrode layers GT0-GT2. The wiring level of conductor layers as bit lines B0 and B1 is different from that of the gate electrode layers GT0-GT2. Therefore, the bit-line interval can be decreased in conformity with the decrease in gate interval, and the integration density can be improved to a large extent in comparison with a conventional structure.
